Specification of Application filed June 19,'

Tol all whom t may concern.'`

Be it known that I, WHITTLnsnY VA. BRAKE, a citizen of the United4 States', residing at PetroleuniJn the county of T rumbull and State of Ohio, have invented c'ertain new and useful Improvements in Tank- Band Saddles', of which the following isy a specification, reference being had therein to the accompanying drawing.

- This invention relates to an improvement in tank b and saddles, and is to be used on tanks of' tankc'ar's, v c

` It is well-known to those who understand the construction of tank cars, that bands pass over the tanks and have their ends suitably connected to the frame of they car.

It is also well-known to those familiar with the construction of tanks for cars, that they are made up of metalplates or sheetshavingV overlapped riveted joints.

v f In tank cars these bands are drawn tightly over the vtanks for the purpose of holding rtl'ie'rn permanently to the frame of the'car,

and hence, the bands engage the outer surface of the tank with considerable pressure.

Where the bands pass over the riveted joints,

theyV engage the rivets and cause undue pressure on the joints, which has been found objectionable for the reason that such uneven or undue pressure isv liable to cause leakage as well as bringing the Istrain on the band at the pointed riveted heads.

Theobjectpof my invention is to construct a saddle which will. rest Vupon the outer. surface o the tank? atf the riveted lapped joints, andfr'ece'ive and support the tank band inv such manner as to prevent 'the prestank car constructions.v V i Vith these'. ends in view, I construct a saddlel which may be composed otone or two parts and which Vyengage the outer sur-y face of the tank at opposite sides ot the lriveted joint with suiic'ient l,thicknessv to supportt'he b'and.- above thek rivet heads of the joint and tapered towardits outer ends, whereby the riveted'joint is relieved of the `direct pressure caused by the engaging the heads of thev rivets.- Y

Furthermore, to provide for the proper engagement 'of the saddle at opposite sides of the riveted joint, that side'adj acent to the` outside lap of the joint has an increased ythickness as comparedv with the thickness of the saddle to the opposite side of the 'the two-piece form' reza/,Serin No. 390,192.

l My improvement consists off'al saddle. Referring nowparticularly'to Figsfl and 2, which showthe preferred one-piece forni ofsad'dle, this comprises an elongated inem loerl 6, which entends'transverse"'the `lapij oint 3,'as shown( The center 7 fofthiselongated member' `6,"is sutiiciently' Vthick-to have-its center 'portion'v 7 in a'plane'fo'utside Aof 'or beyond the heads of therrive'ts, 7, and is provided ,witliro'pe'ni'ngs or v'depressions 8 to receive the outer heads oftherivets 4. From this `centerl 7 the saddle tapers upwardly toward? both -ends as shown, and" the' tank band rpas'ses'fover `and engagesfthe (outer face of the saddle, whereby the band is prevented band 5.

from engaging the outer heads of the rivets 6, preventing it from bringing direct pressure on the rivets and lap-joint, which in use is liable to cause leakage. Thel saddle is made thicker at one side of the lap-joint than at the other, as shown at 9 and 10. This difference in thickness is equal to the thickness of the matrial of which the tank.

shell is composed, whereby the saddle is caused to engage thel tank shell with equal pressure at opposite sides of the lapped 'oint. J For the purpose of preventing the saddle from moving laterally from under the band, the saddle isv provided at its edges with outwardly projecting flanges or projections 11, which are located at oppositeedges ofthe These flanges or` projections will prevent any relative lateral movement of the saddle and the tank'band and thus prevent lateral displacement, andthe outer heads of the rivets whichengageopenings or recesses inY the center of the saddle prevents it from having any longitudinal movement. This longitudinal movement, however, would be prevented by reason of the outward tapers of the ends of the saddle between the band 5 andthe shell, since the band after passing over the saddle engages directly the tank shell 1 and 2, as shown at 12. In this onepiece saddle, it is preferably, though not necessarily, provided at one side of its center with laterally extending portions 13 to extend around and embrace the heads of the Arivets at these points, as clearly shown in Fig. 2. For the purpose of saving metal, the saddle may have suitable sized openings 14. f Y i In Figs. 3 and 4, I have'shown my saddle made in a twopiece form. In this construction, it comprises the two pieces B and C, which are positioned at opposite sides of the lap-joint 3. The inner end 15 of the piece C is made thicker than the inner end l16 of the piece B, and this difference is equal to the thickness of the tank shell 1 and 2. These points 1,5 and 16 of the twopiece form correspond with the points 9 and l0 of the one-piece form and perform the same function.j The inner ends 15 and 16 of the two-piece form are made suiiiciently thick to support the tank band 5 above the outer ends of the rivet heads as the one-piece does and prevents the band from engaging the outer heads of the Vrivets and causing direct pressure onthe rivets and the ylap- `joint, which is objectionable for the reason previously stated. These pieces B and C have projections or flanges 17, at their opposite edges between which the band 5 passes and theyV serve to prevent relative lateral movement of Ythe band and the parts B and C, and therefore prevent lateral displace ment.f The two piecesB and C taper outv ,i It will be understood, of course, that in the form shown in Figs. 3 and 4, it takes the two pieces to make the complete saddle, instead of a single piece, as in Figs. 1 and 2.

I donot limit myself to the precise construction here shown, as variations and modifications thereof may be made without defparting from the spirit and scope of my invention, as ,deiined in the appended claims. Having thus described my invention what Iclaim and desire to secure by Letters Patent is 1 1. The combination with a tank having a lapped riveted joint, of a saddle engaging the tank at opposite sides of the joint and adapted to receive and support a tank band out of engagement Vwith the riveted joint,

the saddle having its outer ends tapered outwardly for the purposel described.v

2. The combination with a tank having a lapped riveted joint, ofa tank band saddle engaging the tank at opposite sides of the joint and having a thickness suflicient to receive and support the band out of engagement with the rivets of the joint, the saddle .at that side of the joint adjacent the outside edge of the lapped joint being thicker than at the opposite side of the joint equal to the thickness of the material of which the tank is composed, for the purpose described.

3. The combination with a tank having a riveted lapped joint, of a tank band saddle ,engaging a tank at opposite sides of the riveted joint, the saddle tapering from its inner portion tojits outer ends and having' at its edges outwardly extendingprojections, whereby it is adapted to' receive a band between the projections and supported out 0f contact with the outer heads of the rivets.

4. The combination with a tank having a lap-joint, of a one-piece tank band saddle having its center portion out of contact with Y the joint and engaging the outer side of the tank at opposite sides of the joint, the saddle tapered fromv its center outwardly and adapted to receive and support a bandout of contact with the lap-joint.

5. The combination with a tank having a 7 riveted lap-joint, of a one-piece tank band saddle comprising an elongated member eX- tending transverse the joint and having a center portion thicker than the projection of the rivet heads, the saddle engaging the support the band out of contact with the tank at opposite sides of the joint and havjoint, the intermediate portion of the saddle 10 ing its ends tapered outwardly, whereby it cut away at and out of Contact with the is adapted to Vreceive and support a band joint to prevent engagement therewith; out of Contact with the outer rivet heads.
